---------------------------------------

             Summary: Router crash when a detach arrives on a link that is processing deliveries
                 Key: DISPATCH-1153
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1153
             Project: Qpid Dispatch
          Issue Type: Bug
          Components: Container
    Affects Versions: 1.4.0
            Reporter: Ganesh Murthy
            Assignee: Ganesh Murthy
             Fix For: 1.5.0


When a detach arrives on a link when the router is in the middle of processing deliveries on the link, the detach handle code clears out the undelivered list when the qdr_link_process_deliveries in transfer.c is still in the middle of processing it.

This happens in-between two locked code sections.
